Definitions

  • the present invention relates to the field of block-shaped building elements, including bancher blocks of the crawling type, and relates to a composite building block of the block-type insulation.
  • these blocks made entirely of a carrier material, those which are in the form of a profiled hollow body of parallelepipedal shape whose side walls delimit either one or at least two cells open towards the above and below this block. They have a profiled shape in the stacking direction, with a section 8 (two cells) or H (with a double transverse wall defining a cell).
  • a fluid material incorporating a hydraulic binder for example of the concrete type, is injected into the cell alignments resulting from the superimposed rows of blocks, in order to create the framework of the resulting wall after solidification.
  • insulating blocks which are generally constituted by a structure consisting of an assembly of two constituent elements, one of which, located on the internal side of the construction, is a block of carrier material (concrete, wood-cement or other) and the other, located on the outer side of the construction, is a rigid insulating member, usually expanded polystyrene or polyurethane or the like.
  • Such a concrete block constituting an insulating block generally comprises one or more assembly sites with an insulating element which consist of one or more male parts or tenons, intended to fit tightly in a complementary female part or mortise, formed in the corresponding insulating element, and whose shape of said male / female parts, for example dovetail, is determined from in such a way that their mechanical connection can oppose their separation when they are subjected to an external traction force.
  • one or more cells formed by the meeting of the concrete part with the corresponding complementary insulating element, constitute, when mounting the blocks on each other for the construction of a wall and as indicated above for conventional blocks, vertical compartments in said wall which are intended to be filled with concrete, so as to self-lock said blocks on top of each other and to achieve a succession of concrete posts constituting, with the horizontal chaining, the frame of said wall.
  • the object sought in this prior document is to subdivide the structural body of the building block into parts thermally insulated from one another by one or more insulating inserts.
  • the insulating elements in the form of platelets are arranged to be arranged entirely inside the building block, as inserts, that is to say without being in contact with the outer faces of these blocks. of construction and a fortiori without forming an outer side of these blocks.
  • the inner and outer faces of this building block are always formed by the structural body. There is therefore no insulation function on the outside of the blocks.
  • the document FR 2,567,177 discloses, for its part, building blocks comprising a first structural part (agglomerated block) and a second insulating part (plate), the latter being arranged to be mounted / fixed on the first part by an insertion of T-section tabs in adapted grooves and formed in the outer component of the wall of a side face of the first structural part.
  • the walls of the block forming the structural part have a double and multi-cellular constitution around central cells and the grooves are formed by a plurality of slit-shaped cuts in the thickness of the outer skin of the wall of the first part. structural.
  • peripheral attachment of the insulating portion in small grooves and with a recovery only at an outer skin of the wall and on a small surface only does not allow to achieve a resistant assembly between the two components and therefore also limits the thickness of the insulating plate that can be secured and the stresses to which it can be subjected and can be transmitted to the structural part.
  • the present invention aims to overcome at least some of the aforementioned drawbacks of existing solutions, while having at least equivalent performance, or even higher in some aspects.
  • the subject of the invention is a composite building block, of the insulating blocking type, comprising two component parts. rigidly connected to one another by multiple mechanical connections, one or the first of said constituent parts being made of a carrier material, comprising at least one cell, traversely open in a stacking direction of said block, and intended to be filled with concrete or a similar loaded hydraulic binder, the other or second constituent part being made of a rigid insulating material having a substantially solid structure in the form of a plate or block, the multiple mechanical bonds comprising tenon / mortise connections obtained by mutual engagement by interlocking sites and formations of shapes complementary parts of the two constituent parts in the stacking direction of the building block, the first constituent part comprising two opposite main walls, parallel and connected transversely by at least two secondary walls delimiting, in cooperation with the two main walls, said at least one cell, and the second constituent part being secured to the first constituent part at a first of its two main walls, building block characterized in that the female sites and the mutually nested male formations of the
  • the figures 1 , 2 and 3 in particular, all show a composite building block 1, of the block-type insulating type, comprising two component parts 2 and 2 'rigidly connected to each other by multiple mechanical connections 4, of which one or first 2 of said constituent parts 2 and 2 ', made of a carrier material, comprising at least one cell 3, traversingly open in a stacking direction DE of said block 1, and intended to be filled with concrete or a similar loaded hydraulic binder, and whose other or second constituent part 2 ', made of a rigid insulating material, having a substantially solid structure in the form of a plate or block.
  • the multiple mechanical connections 4 comprise tenon 5 / mortise bonds 6 obtained by interengagement by interlocking sites and formations of complementary shapes of the two constituent parts 2, 2 'in the stacking direction DE of the building block 1.
  • the first constituent part 2 comprises two opposite main walls 7 and 7 'parallel and connected transversely by at least two secondary walls 8, 8' delimiting, in cooperation with the two main walls 7, 7 ', said at least one cell 3, and the second constituent part 2 'is secured to the first constituent part 2 at a first 7 of its two main walls 7, 7'.
  • the female sites 6 and the mutually nested male formations of the tenon / mortise connections are located in the material thickness of the aforementioned first main wall 7 of the first part 2, that said sites 6 and said formations 5 extend, in the DE stacking direction, only over a fraction of the height H of the building block 1, and that the female sites 6 and the male formations 5, of complementary profiled shapes, have in section in a plane perpendicular to the stacking direction DE, a trapezoidal shape, the multiple mechanical connections 4 between the two component parts 2 and 2 'thus corresponding to a multiple assembly with dovetails.
  • the second constituent part 2 ' is in intimate surface contact with the outer face 9 of the first 7 of the two main walls 7, 7' of the first constituent part 6, preferably by covering it completely, the second part 7 'being advantageously in the form of a parallelepipedic block of constant thickness, (except for the extra thicknesses of the formations 5).
  • the female sites 6 are formed in the first main wall 7 of the first part 2, in the form of cuts passing through the entire thickness of said wall 7 and open or opening at the the edge 9 'of said main wall 7 corresponding to the upper edge in the stacking direction DE, and the male formations 5 of conjugate forms consist of projections in one piece of the second constituent part 2', projecting with respect to its surface in contact with the outer face 9 of the first main wall 7 of the first part 2.
  • the front face 5 'of the male formations 5 is in direct contact with the concrete which will be poured into the cells 3, from which it results in this way an additional function of material adhesion and locking in position and of complementary bonding (after hardening of the concrete) for the second part 2 '.
  • the attachment may even be improved by providing a non-planar surface for the front surface 5 ', for example fluted or ribbed (not shown).
  • the first and second component parts 2 and 2 ' have identical dimensions in the stacking direction DE and the female sites 6 and the male formations 5 present in this direction DE of dimensions such that in the assembled state of the block 1 the two constituent parts 2 and 2 'are opposite and mutually level.
  • the multiple mechanical connections 4 comprise two tenon 5 / mortise connections 6, the two female or mortise sites 6 of which are formed in the first main wall 7 of the first part. constitutive 2, in the form of blanks.
  • the two male dovetail formations 5 of the second constituent part 2 ' form between them a tail-tail 10 receiving a dovetail portion 10' defined in the first wall main 7 of the first constituent part 2 between the two female sites 6 forming tail-tails for the two male formations 5.
  • the angle of inclination ⁇ is advantageously between 40 ° and 60 °, preferably between 45 ° and 55 °, advantageously of the order of 50 °.
  • the female sites 6 extend in depth, in the stacking direction DE, on at most half of the height H of the first main wall 7 with a solid structure of the first constituent part 2.
  • the first constituent part 2 is made of wood-cement or fiber cement and the second constituent part 2 'is made of an expanded synthetic material, such as polyurethane foam or expanded polystyrene.
  • the subject of the invention is also a method of manufacturing a block 1 as described above consisting in separately producing a first constituent part 2 forming a carrier component and a second constituent part 2 'forming an insulating component, and then assembling them by by means of multiple mechanical connections 4 of the tenon type 5 / mortise 6 by fitting the tenons of the second part 2 'into the mortises of the first part 2 and by sliding the two constituent parts 2 and 2' with respect to the other, and possibly to lock the assembly.
  • This process is characterized in that it consists in manufacturing the first constituent part 2 with a first solid main wall 7, preferably in the form of a profiled element, for example coming from extrusion of wood-cement or fiber cement, and then digging the female site (s) 6 forming mortise (s) in the thickness of said first wall 7 by means of a conical or frustoconical cutter 12 ( Figures 4A, 4B and 5 ).
